Erratic NX 12-24mm operation...

...any thoughts about the following:

While using an NX500+12-24mm combo yesterday I encountered some strange behavior. On a number of photos one or more of the following occurred:

  1. badly missed focus/nothing in focus (with zero camera shake and high shutter speed)
  2. strange over/under exposures for the settings used
  3. approx. 1+ second delay in the shutter firing after fully pressing the shutter button

None of these have ever happened with the NX500 and any lens I own except point #1 for the 16-50pz. I have used the NX12-24 for only a short while, but it has performed flawlessly with the NX500.

After an error I tried detaching/reattaching the lens and it worked perfectly again, but sometimes for just one shot. I have a second NX500 and after trying the lens on it, point #3 occurred on the second photo. Detaching/reattaching helped some again.

Below is an example of a photo that exhibited point #2 - under exposed by one full stop. The same settings worked very well for photos taken at the same time/spot. Included is the finished product. This photo was no problem to recover, but some were a complete washout. For the NX500 not to be able to recover from a missed under exposure - that's a bad photo - and I had several of those.
